Winchester assembled after the parts were finished
So it is common to see some small scratches where the sight went on. Yours look heavy and the staking is not like Winchesters I've seen. The photos are small, but the stake marks look circular.
Winchester assembled after the finish was applied.
The type 2 bands are also unmarked but can be identified as Winchester by certain characteristics. Winchester used a very ordinary way of staking almost a smear across the pin. Bill, I agree with you about the use of the type 3.
Inland: aren't you talking about Inland carbines?
They were finished as an assembly and the band was placed near the barrel/receiver joint leaving a lighter color. This carbine is a Winchester.
